Here's what to watch for in Delaware, where polling places will be open from 7:00 am to 8:00 pm, Eastern Time. If voters are in line waiting to vote at closing time, they may cast their votes even if it is done after 8:00 pm.[1] Election officials are predicting high voter turnout as a result of the large number of primary contests among Republicans and Democrats, as well as numerous local races and statewide contests.[2]

U.S. House

Delaware has one congressional seat on the ballot in 2012. A total of 4 candidates filed to run, made up of 2 Democratic challengers, 1 incumbent, and 1 Libertarian. Including states with primaries tomorrow, a total of 429 U.S. House seats have held primaries. Thus far, 55.01% of possible primaries have been contested. Delaware's contested figure of 50% (1 out of 2 possible party primaries) is slightly less competitive than the national average.

State legislature

There are 62 total legislative seats with elections in 2012 -- 41 Senate seats and 21 House seats.

There are 14 (22.58%) contested Democratic primaries and 6 (9.68%) contested Republican primaries. Thus, there will be 20 (16.13%) races tomorrow with at least two candidates on the ballot. The 16.13% figure of total contested primaries in Delaware is lower than the current national contested average of 18.40% for states that have had filing deadlines.

District 3: Incumbent Robert Marshall first assumed office in 1978 and faces primary competition from two challengers, Eric M. Anderson and Timothy J. Meades, Sr. in the Democratic primary. The winner will face no major party competition in the general election, and is all but guaranteed the winner of the district seat.

District 2: Incumbent Stephanie Bolden first assumed office in 2011. She will face challenger Arthur Scott in the Democratic primary. The winner will face no major party competition in the general election.

District 22: Incumbents Nick T. Manolakos, who first assumed office in District 20 in 2007, and Joseph Miro, who first assumed office District 22 in 1999, will face off for the Republican nomination. The winner of the incumbent vs. incumbent primary will take on Democratic candidate David E. Ellis in the general election.

District 39: Incumbent Daniel Short, who first assumed office in 2003, will take on challenger Patrick J. Murray not just for the Republican nomination. The winner will face no general election competition, and will be all but guaranteed the district seat.
